CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 293,346, dated February 12, 1884.

Application filed December 11, 1883. (No model.)

.To all when t may concern:

Be it known that I, DAvrD M. MONROE, a citizen of the United States, residing at Baltimore city,.in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Can-Soldering Machines, of which the following is aspeciication, reference being had therein to the accompanying drawings.

My invention relates to improvementsin cansoldering machines in which the side seams of sheet-metal cans are soldered; and the objects of my improvements are, iirst, to

A provide nieanswhereby the outside of the seamed bodies shall all measure alike, second, to adapt asingle gaging "device to a rotary conveyer, so that the bodies placed or gripped thereon may be sized by one gaging apparatus, which simplifies the machine, and the soldering, being done, in the usual manner, by an operator with a hand'copper, at a point on the conveyer away from the gaging device, does not subject the same to the heat and flux therefrom; and, third, to provide mechanical means whereby the several parts may be rapidly and-accurately operated. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a side elevation of the machine; Fig. 2, a topview of the same; Fig. 3, an en. larged view of the gaging device, part of which is in section; Fig. 4, top View of same; Figs; 5 to 13, views of the gaging-heads.

Similar letters refer to similar parts through out the several Views.

The top A and legs B constitute .the frame of the machine, to which is attached a vertical shaft, C, on which a rotary conveyer, D, rotates, the latter having a vertical adjustment by which it may be set to accommodate the differentheights ofthe can-body-gaging device.

On the shaft Gis a collar, a, which is held to its place by a set-screw, a', and to which is .attached a pocket, a?, carrying within -it a spring and pin, a3. The spring, pressing on while the 4can-body R is being` gaged; but on exerting sufficient power to the conveyer D to overcome the spring, it may be rotated to the following notch, and so on, stopping and hold` ing the same each time at its proper place.

On the several arms of the conveyer D are and attached to the outer end of same is a knife, 02,' which is pressed to the arms c by means of the spring c3 and rod 04,' holding the can-body R, when there placed, firmly to its proper size and position, while the soldering is being done, and until released therefrom. The lever c and knife c2 are operated by the rock-arm i, pivoted at i to the bearing E, (see Fig. 1,) and projecting below the frame-top A, there connecting with a rod, i2, `which extends under the frame-top vto the end of same, and projecting therefrom, carrying a breastplate, i". Onv pressing the breast-plate i inward, the upper end of the rock-arm i will bear down on the lever c', thereby raising the knife c2, allowing the can-body to be placed, adjusted, gaged, Ste. The heads F F consist, first, of semi-annular outside gages, d, provided with projecting flanges d', which project over the end of the can-body on the outside, Vpermitting the canbody to be expanded only to a given diameter, said diameter being changeable by means of the slots f and screws f', which 'will permit the gages d to be moved inward or outward 5 second, of inside expanding-jaws, e, which are j movement, which is imparted thereto from the 95 rock-arm k, which is pivoted at 7c', the upper end of same projecting through an elongatedv slot, s, in shaft t', and into a slot, s,'in the rod a.

On the outer end of the rod. a is secured a collar, a', which bears on the spring a2, the

IOO

other end of which bears on the shoulder vt2 in the shaft t. By an inward movement of the arms 7c 7c, the shafts tf t and their attachments approach each' other until the stops '1; on the shafts t t come in contact with the bearings E,

.which prevents the shafts t t moving farther forward. The rock-arms 7c continue to advance, and with them the rods n, the springs n2 allowing the continued movement of the rods a, which expands the jaws e, thereby pressing the can-body R outward against the outside gage, d, always keeping the outside'of the canbody the same size. The stops o are set to stop the heads F F at a point sufficiently apart to allow the can-body to enter the heads F F only a given distance, thereby preventing the same from injuring the ends of the can-body. To the lower end of the rock-arms k is attached a connecting-rod, k2, which is attached to an equalizing-bar, g, provided with springs q and guides gf. To the bar q is connected the treadle y by means of a rod, y.

In working the above invention, if the gages d should wear, as in devices of like kind heretofore, the deficiency caused thereby may be obviated by moving the gages d inward, the slots f and screws f permitting the same.

In operating the machine one man and a boy are required. The boy places the rolled blank on the arm of the conveyer-that is, between the gaging-heads--ii rst raising the knife c2 by pressing the breast-plate i inward, then gaging the can-body by depressing the treadle "y, and holding the same down until releasing the breast-plate i3, which permits the knife c2 to clamp and hold the can-body on the arm of the conveyer D. The treadle g/is then released, allowing lthe heads F F to draw back from the can-body. The conveyer is then rotated by the boy until the arm following comes between the gagingheads. rIhe operator or sea-mer solders the seam, in the usual manner, with a hand-copper, standing at right angles to the gaging device, in the direction therefrom in which the conveyer rotates, thereby permitting the seamed bodies to move three-fourths the circle traveled by the conveyer D, allowing the seamed bodies ample time to cool, which are then removed by the boy at the gaging device.

Having fully described my invention,what I desire to claim and secure by Letters Patent l. The combination of a rotary conveyer, D, having attached thereto projecting arms c and clamping-knives c2, and a gaging device provided with gages d, inside expanding-jaws, e e,

'and mechanism that will force the jawsl e e apart, as set forth, and for the purpose as herein specilied.

2. In a can-body-gaging device, the combination of two reciprocating heads, F F, provided with outside gages, d, inside expandingjaws, e @,sand mechanism to force the jaws e e apart, whereby Aeach end of the can-body will be gaged at the same time.

3. The' combination of the outside gages, d,

inside expanding-jaws, c c, a reciprocating ca rrier or shaft, t, attached thereto, and mechanism contained therein which will force apart the jaws e c when they cease tomove in the direction of the can-body.

4. In a can-seaming machine, the combination of a conveyer having a vertical adjust ment and a device to stop and hold the conveyer, whereby the conveyer may be adjusted vertically by the vertical adjustment of the
